[−][src]Trait wasabi_leb128::ReadLeb128

pub trait ReadLeb128<T>: Read {
    fn read_leb128(&mut self) -> Result<(T, usize), ParseLeb128Error>;
}

A trait that extends readers (implementers of the io::Read trait) with a method to parse LEB128 encoded primitive integers.

Required methods

fn read_leb128(&mut self) -> Result<(T, usize), ParseLeb128Error>

Reads an LEB128 encoded integer of type T by decoding a sequence of bytes from self.

If successful, it returns the parsed value and the number of bytes consumed from self, otherwise a ParseLeb128Error.

Example

use wasabi_leb128::ReadLeb128;

// Wrap the array in an io::Cursor, which implements io::Read.
let mut buf = std::io::Cursor::new([0x80, 0x01]);
let (value, bytes_read): (u8, usize) = buf.read_leb128().unwrap();
assert_eq!(value, 128);
assert_eq!(bytes_read, 2);
